Title: tssm chem question impossible
Post by: gmx on June 07, 2010, 09:53:33 am: Does anyone have any idea how and what to answer TSSM chemistry 2010: Short answer question 1c?

Post by: cindyy on June 07, 2010, 10:43:34 am: how is that impossible? :o
peak area is just 3:2:3 - the number of H bonded to the carbon
H-atoms in the neighbouring is 2:3:0 -the last one is 0 because it is bonded to an ester
number of splits are 3:4:0

hope that helped!

I agree, I was thinking do they want total number of peaks in the end (in high res NMR) or do they want to know how many peaks each single peak will split into.
